SPBCIFICA'ION orming part of Letters Patent Na 305,883lv dated September 30, 1884.

` Application filed hzlay 23, 1884. (No modem To rtl whom it `ntfitz/ cmwern:

Be it known that I, WILLIAM G. BAUM- GARDNER, of Filer City, in the county ot' Manistee andState of Michigan, have invented a new and Impr'oved Circular-Saw Lifter, of`

which the following is a fnll, clear, 'and exact description.

My invention consists of a yoke having ahandle pivoted on each of its parallel bars, which has a cam-log on one side of the pivot, adapting the two handles to form gripping-jaws, between which the toothed edge of the saw may be inserted,-so as to be gripped and held securely by the leverage of the handles and frietion of the jaws for a simple and convenient means of lifting and handling circular saws, as hereinafter fully described.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the, figures.

Figure 1 is aplan view of myimproved circolor-saw lifter. Fig. 2 is a transverse section on the line a' x of Fig. '1, with the sawplate between` thejaws, and Fig. 3 is a side elevation of the lifter and aportion of the sawplate.

I make a strong yoke, a, with parallel bars b, a little wider apart than the thickness of a saw-plate, c, and having lugs cl on the upper side, between which I pivot handles e, having cam-lugsf eccentric to the pivot-bolts g, and being suitably turned upward with relation to the handles and the yoke to grip the sawplate between them when the holder is held up by the handles, so as to hold the saw by the friction of the grip ofthejaw-lugs, as is clearly shown in Fig. 2, the grip of the lugs being caused by the weight of the saw and the 1ev-` erage of the handles. The handles will pref- 41 erably be constructed in the loop-form herein represented; but they may of course be made in any other approved form, and both the handles and the yoke a will be made of forged iron or of malleable iron, When required, for 4 strengt-h.

A It will be seen that this simple saw-lifter will afford a. ready means for taking hold of a circular saw for lifting` it, especially that side of the saw on which the teet-h point up- 5 ward, for which there is now no means in use, eXce-pt to grip the toothed edge by the hands, which is dangerous, and at best cannot be very stron gly held because of the points of the teeth, which prevent a strong grip. 5 w Having thus described myl invention, I claim as new and desire to secure by Letters` Patent- 1. The improved circularsaw lifter con sist-ing of the yoke a, having cam-level' handles pivoted to its parallel bars b, and adapted to'grip a sawplate inserted between said bars of the yoke and the lever-handles, substantially as described.

2. The combination, in a circular-sawlifter, of the yoke a, having lugs (Z on its parallel bars b, and the lever-handles e, having ca-inlugs f, and being pivoted between the lugs d of said bars, substantially as described.
